Let's convert the final speed of the car into m/s:

We can find the acceleration of the car by using:

where vi=0 is the initial speed of the car, vf=26.4 m/s the final speed, a the acceleration and S=125 m is the distance covered.
By substituting numbers and re-arranging the formula, we find:

And then, we find the force by using Newton's second law:
